Filed: 1932-06-01
Abstract: 389,682. Exercising - apparatus. BATH, C. M. H., 302, Heerengracht, Amsterdam. June 1, 1932, No. 15577. [Class 132 (i).] Exercising-apparatus comprises a plurality of members such as straps or cords stretched substantially parallel to the floor, a friction member in frictional contact with the straps and movable relatively thereto, and a handle or grip device associated with the friction member and the straps and adapted to be moved by hand to produce relative movement against frictional resistance between the friction member and the straps. As shown in Figs. 1 and 2, two straps 3, 3 are attached at one end to the hooks 1, 1 and at the other to cords 5, 5 provided with stretchers 6, 6 and fixed to hooks 2, 2. The friction member comprises two wooden rods, 7, 8 above and below the straps 3, 3 respectively, and adjustably connected by bolts 9 and wing-nuts 10. To rod 7 is adjustably connected by bolts 12 and wing nuts 13 a handle 11. The friction on pulling bar 11 is greater than when pushing it. A seat 15 is mounted on rubber-tyred wheels 16 running on rails 18 provided with stops 19. A foot strap 21 is attached to eyes 22. In a modification a single cross-bar with slits or holes at the ends through which the straps pass, and to which bar the handle is adjustably connected as above, may be employed as the friction member. In a further modification endless cords passing twice over fixed pulleys, or pulleys only rotatable with difficulty against frictional resistance, and to which the cross-bar handle is attached, may be employed. In a still further modification clips adapted to grip the straps when pulled in one direction and to release them or grip them less tightly when moved in the opposite direction may be employed.

Abstract: 1,139,781. Planar transistors. ASSOCIATED SEMI-CONDUCTOR MFRS., Ltd. 7 April, 1966, No. 15612/66. Heading H1K. A deeper, lower-resistivity portion 6 of the base region is formed by diffusion through a first opening (4, Fig. 1) in an insulating layer 3, a contiguous shallower higher-resistivity base portion 11 is then formed by diffusion through a second opening (9, Figs. 3 to 6) in the insulating layer 3, and an emitter region 14 is subsequently formed by diffusion through the same second opening. A relatively thin insulating layer (13, Fig. 4) may be formed in the second opening during diffusion of the second base portion 11 and removed by etching without appreciably affecting the remainder of the thicker insulating layer 3. Ohmic contact material 20, 21 is deposited in further openings 18, 19 in insulating layers 8, 16 formed in the first and second openings, and one or both of these further openings may coincide with one or both of the first and second openings. All the openings are produced by photo-processing techniques. The method may be extended to the manufacture of a multiple-emitter transistor (Figs. 15 and 16)with ohmic contacts in the form of (possibly interdigitated) aluminium layers (23, 24) overlying the insulating layer (3) of silicon oxide. Reference has been directed by the Comptroller to Specification 1,018,763.

Title: Improvements in or relating to sporting-guns
IPC: F41A21/06
Filed: 1947-06-13
Abstract: 630,640. Sporting guns. LAMBERT, M. M. V. June 13, 1947, Nos. 15677 and 15678. Convention dates, June 21, 1946 and March 4, 1947. [Class 119] A double-barrelled sporting gun of the swinging barrel type has its barrels C1, C2 jointedly connected and pivotally mounted by a trunnion 4, 5 extending into the space between them in the neighbourhood of the cartridge chamber on a plate 9, the plate being slidably mounted on a breech member 17 fast with the stock 8. The plate has its movements controlled by a bolt 18. In the construction shown the barrels are pivotally connected together at their muzzle ends and are normally held together by a pin and slot device midway of their lengths. A boss 5 of one barrel C1 fits into a hole 10 in the plate 9, and a boss 4 of the other barrel fits into the boss 5. The plate has recesses 11, 12, forming limbs 26<SP>1</SP> which fit slidingly into longitudinal grooves 26 formed on the sides of the breech member 17 which is fitted to the stock 8. This member has recesses 23 on its front face for receiving the rear ends of the barrels when the plate is in its rearmost position, as shown. In this position the plate is locked by the face 27 of a vertically slidable bolt 18 actuated by a thumbpiece 22. When thumb-piece 22 is actuated the bolt is lowered, thus moving the plate and barrels forwards until the barrel ends are free from the recesses 23. The barrels are now pivoted about the bosses 4, 5 and during such movement a cam groove 14 in a plate 13 which slides in the recess 11 operates members to eject the cartridge cases, and a second groove 15 by engaging a projection on one barrel causes the plate to move to the rear; whereupon pins 16 serve to cock the firing hammers. The triggers 21 are located in a recess in the stock, the latter being apertured as shown to enable the triggers to be actuated.

Title: Toy discharge mechanism
IPC: F41B7/08
Filed: 1975-04-08
Abstract: 1494503 Toy guns &c. BRITAINS Ltd 8 April 1975 [9 April 1974] 15735/74 Heading A6S A toy gun, &c. comprises a breech-loading member which is normally biassed into a position preventing a firing member from striking a projectile loaded through the gun, &c. muzzle. As shown, a breech-loading member 9, Figs. 2, 6a is gravity biassed so that when a spring-urged firing pin 5 is pulled back to its cocked position, Fig. 3, and turned to latch its arm 5a in a recess 11 of the gun block, the breech-loading member falls to obstruct a passage 10. Thus if the firing pin 5 is released, it merely latches into a recess 20, Fig. 3 in the breech-loading member 9; accordingly if a projectile has been loaded into the muzzle 2 of the gun, it is not ejected. To load the gun, the breech-loading member 9 is raised from the Fig. 3 -to the Fig. 4 position. A simulated shell 15 is inserted via a groove 19 in the gun body through a keyhole slot 12, Fig. 6a in the breech-loading member 9 to the position shown in hatched lines, Fig. 4. The breech-loading member 9 is then released and falls to the position shown in Fig. 5. The firing pin 5 may now be twisted to its release position, its compressed spring 7 forcing the firing pin arm 5a forward to strike the shell 15, which as ejected through the muzzle 2, the firing pin arm 5a -entering the breech loading member keyhole slot 12 and returning to the Fig. 2 position. Instead of being gravity biassed, the breech loading member 9 can be spring biassed. A groove-22 at the bottom of the gun breech is so dimensioned that a shell, &c of less diameter than a desired safety limit will fall into it and then cannot be fired.

Title: Improvements in or relating to axle counting for railway signalling
Inventor: BROWN ANDREW
IPC: B61L1/16
Filed: 1948-06-11
Abstract: 683,022. Axle-counting equipment for railway signalling. STANDARD TELEPHONES & CABLES, Ltd. June 11, 1948. No. 15813/48. Class 105. Axle-counting equipment to discriminate between the direction of travel over two closely adjacent track contacts comprises electric discharge tube equipment responding in a different manner according to the direction of travel and so giving signals denoting either entry into or exit from the track section at that point where the two closely adjacent track contacts are situated. The equipment comprises a system of gaseous discharge tubes in a resistancecapacity circuit arrangement the discrimination arising from the different phase of voltage decay in resistance-capacity lines applied to the grids of the discharge tubes. The two closely adjacent track contacts may be of the mechanical treadle or of the inductive type. Fig. 1 shows the track layout and Fig. 2 shows the discharge tube arrangement for directional discrimination. As shown in Fig. 1, the two ends of a track section 1-1A are each respectively provided with two inductive contacts 4/4A 5/5A each contact comprising a primary winding energized from an oscillator 3 and a secondary winding influenced on passage of a wheel to actuate a contact, (such as 10 or 11, Fig. 2) in a direction discriminating unit denoted generally by 7 in Fig. 1. As a wheel passes the two closely adjacent track inductive contacts 4, 4A it will first actuate contact 10, Fig. 2, then contact 11 with 10 still actuated ; contact 10 will thereafter release with contact 11 still actuated and finally contact 11 will release. Movement of contact 10 from the position shown applies voltage to a discharge tube 13 and to a resistance-capacity line 16 but the tube does not strike since resistance 17 reduces the anode voltage. When very shortly afterwards the contact 11 moves from the position shown a tube 14 does strike since paralleling of the resistances 17 gives sufficient anode voltage ; tube 13 does not however strike since the grid voltage has fallen to the resistance-capacity line 16. The striking of tube 14 is however without effect since the pulse from transformer 19 is applied at this moment to the grid of a discharge tube 15 without anode voltage. When however contact 10 is released to the position shown the tube 14 is extinguished and the resulting pulse from transformer 19 is applied to the grid of tube 15 the anode of which now has voltage applied thereto ; tube 15 therefore, strikes and gives an in-counting pulse in line 20. If the track contacts are passed in a reverse direction then in a similar manner a tube 12 is struck to give an out-counting pulse in line 22. The arrangement is such that "buffering" of the vehicles of a train does not give false counting. Specifications 447,866 and 527,426 are referred to.

Abstract: 612,396. Resilient mountings. SAXON ENGINEERING CO., Ltd., and WINDSOR, G. PARRY-. May 24, 1946, No. 15873. [Class 108 (iii)] Means for supporting are: ciprocating or oscillatory member comprises a plurality of bonded rubber sandwichlike supports, each consisting of two parts in V or inverted V arrangement as viewed transversely, so that longitudinal movement of the member is resisted only or mainly by shear of the rubber, 'while movement in all transverse directions is resisted by compression and/or tension of the rubber with or without a shear component. In the construction shown in Fig. 2, the'body 8 may be supported at one or more points on either side by two rubber sandwich mountings 4, screwed to a base frame member 6. Alternatively, the two mountings may be of integral form, the rigid members being of V or inverted V-shape in cross-section. Metal plates arranged parallel with the bonded surfaces of the rigid members may be bonded in the rubber to increase the ratio of shear to compressive resistance. In side elevation, the rubber elements and corresponding bonded surfaces of the rigid members of the mountings 4, may be of rectilinear or curvilinear formation and may be inclined to the horizontal. A curved portion may be formed at one end to produce a lifting effect. When the surfaces are curved longitudinally the mountings on one side of the body may be so arranged that their respective surfaces have either common or different centres of curvature. Spigots or other registering means may be used to maintain coacting parts in their proper relative positions.

Title: Electronic discharge tubes
IPC: H01J17/58
Filed: 1931-06-04
Abstract: 379,736. Electron discharge tubes. STANDARD TELEPHONES & CABLES, Ltd., Columbia House, Aldwych, London.- (Assignees of Bond, D. S. ; 51, Clark Street, Brooklyn, New York, U.S.A.) June 4, 1931, No. 16230. Convention date, Sept. 17, 1930. [Class 39 (i).] In an electron discharge tube comprising a cathode and two anodes, as in a full-wave rectifier, the cathode is in the form of a coiled or folded ribbon so disposed as to constitute a physical and/or electrostatic shield between the anodes. Fig. 1 shows one arrangement of a high vacuum full-wave rectifier tube in which the cathode is in the form of a nickel ribbon 15 coated with alkaline-earth oxides, e.g. barium or strontium oxides, wound helically around insulating sleeves 21, Fig. 3, on supporting rods 19 attached at one end to leading-in wires 17, 18 and spaced at the other end by an insulating plate 20. Annular spacers 22 between adjacent sleeves 21 prevent contact between adjacent turns of the ribbon, the ends of which are connected to wires welded one to each of the rods 19. Each anode 16 is a rectangular metal plate welded along a central ridge 25 to a leading-in wire 26, 28 anchored at its upper end to the plate 20. Magnesium ribbon 30 adapted to be vaporized to fix residual gases is carried in a dished disc 31 supported by a wire 32 from the leading-in wire 17. An easily ionizable gas or a vapour-producing substance such as a globule of mercury 33 provides the conducting filling. Fig. 5 shows, with the parts dismantled, a modification employing a similar cathode structure with a somewhat wider ribbon 15, this structure being surrounded by a heat-reflecting shield 34 of bright metal supported from the plate 20, and the anodes 35 being in the form of semi-cylinders supported from the plate 20 and from the leading-in wires 26, 28. A central rectangular opening is provided at each side of the shield 34 for the passage of the discharge and arcing between adjacent edges of the anodes is prevented by metal shields 42, 43 supported from the plate 20 and from the leading-in wires 17, 18. Each anode may be provided with a central aperture 44 for observation of the discharge. In a further modification, Fig. 7, the anodes in the form of discs 48, 49, preferably of graphite, are supported by leading-in wires 46, 47 passing through an inwardly projecting stem 45 at one end of the enclosing vessel (not shown), and the cathode in the form of a suitably coated zig-zag metallic ribbon 50, Fig. 8, is provided with leading-in wires 52, 53, 57, 58 parsing through an inwardly projecting stem 12 at the other end of the vessel. The wires 57, 58 connect the lower end of the ribbon to one terminal, the wires 52, 53 connect a metal box 51 surrounding the ribbon to a second terminal, and the upper end of the ribbon is connected by a yoke 59, wires 60, 55, 54 to the box the wire 55 being supported from the stem 45. Rectangular openings for the passage of the discharge are provided in the sides of the box 51 adjacent to the edges of the ribbon.
